Research Topic The introduction of a carbon tax in Australia would have implications for economic and environmental sustainability. Obviously in the longer term the aim of the tax is to promote environmental sustainability but in the short term there will be implications for economic sustainability for a range of businesses and households. Using a range of current sources including reports and newspaper articles discuss the short and longer term implications of a carbon tax for the tourism and hospitality

Carbon Nanotubes Abstract Carbon nanotubes (CNTs) are a recently discovered allotrope of carbon. They take the form of cylindrical carbon molecules and have novel properties that make them potentially useful in a wide variety of applications in nanotechnology‚ electronics‚ optics‚ and other fields of materials science. They exhibit extraordinary strength and unique electrical properties‚ and are efficient conductors of heat. Inorganic nanotubes have also been synthesized. A nanotube is a member

thousand people fall victim to carbon monoxide poisoning and over one thousand five hundred die per year of this gas so deadly‚ it is referred to as the "silent killer"("What Is Carbon Monoxide?"). Carbon monoxide‚ or CO for short‚ is a flammable‚ colorless‚ odorless‚ tasteless gas that is produced during incomplete combustion of fuel and it’s ability to do harm resides within the lack of knowledge and understanding of this gas by society. To remain safe from carbon monoxide poisoning‚ one must comprehend

2013 Carbon Footprint Until very recently‚ most people had never heard of a “carbon footprint.” Now‚ all of a sudden‚ the phrase is hard to avoid. In an age of slick slogans‚ fast fashions and fickle fads it’s easy to assume that this is just another quirky passing gimmick. But it could well be the most important concept of our time. A carbon footprint is the amount of carbon dioxide (CO2) emitted as a direct or indirect result of an activity (Yarrow‚ Joanna. How to Reduce Your Carbon Footprint:

Crystal Lewis 9/21/10 Period 1 Carbon Dioxide Carbon Dioxide is the infrastructure of all life on earth. Every human being and animal needs it to survive‚ making it an essential compound. In order to survive‚ humans and animals must give off carbon dioxide to take in oxygen‚ whereas plants must take in the compound and give off oxygen. Carbon Dioxide has numerous unique characteristics‚ properties‚ and safety measures that everyone should be aware of. Being aware of this compound and what it

SUSTAINABILITY ASSIGNMENT 1 KHANH NGUYEN 1001974 THE NATURAL CARBON CYCLE Carbon dioxide (CO2) is one of the biogeochemical cycles which the fourth most common elements on Earth. It is also a basis of all life and continually cycled and globally existed. Carbon dioxide is obtained from various sources‚ including emissions from volcanoes or industries and combustion products of organic compounds and the respiratory activity of living organisms. Carbon dioxide not only going into the atmosphere through the

Carbon Footprint The term “carbon footprint” refers to the amount of carbon dioxide we emit into the air every year. C02 is produced by many sources and is the gas responsible for Global warming and alarming changes in our climate. As we use our resources‚ the negative impact on our environment increases. The more C02 emitted in the air the more our ozone layer is affected. C02 is a natural gas and is always being emitted and absorbed to and from the air. There is a certain amount of carbon

Empirical and Molecular Formula | Key Concepts * Empirical Formula of a compound shows the ratio of elements present in a compound. * Molecular Formula of a compound shows how many atoms of each element are present in a molecule of the compound. * The empirical formula mass of a compound refers to the sum of the atomic masses of the elements present in the empirical formula. * The Molecular Mass (formula mass‚ formula weight or molecular weight) of a compound is a multiple of the empirical

Carbon is the fourth most abundant element found on Earth‚ and is essential to all life as we know it. It is found in all living substances‚ and is essentially the key element for life. Because the carbon atom has the ability to form bonds with up to four other atoms‚ it can help form solid minerals (such “ limestone)‚ ‘squishy’ organisms (such as plants and animals)‚ and it can be dissolved in water. Carbon is also present in rocks‚ dissolved in rivers‚ lakes and oceans‚ and is in the atmosphere
